Abstract Background The aim of this study is to describe clinical characteristics, diagnostic and therapeutic procedure (polysomnography and continuous positive airway pressure (CPAP)/bi-level positive airway pressure (BPAP)), comorbidity, length of hospital stay (LOHS), discharge destination, and in-hospital mortality (IHM) of patients hospitalized for obstructive sleep apnea (OSA) in Spain over a 5-year study period. Methods We included all patients who were hospitalized for OSA (ICD9-CM code 327.23) as primary or secondary diagnosis between 2008 and 2012. Data were collected from the National Hospital Discharge Database, covering the entire Spanish population. Results We identified 196,769 discharges of patients admitted for OSA. The number of patients with OSA as primary or secondary diagnosis increased from 2008 to 2012 from 5358 to 7992 and 14,916 to 51,135 respectively. The mean age was 50.7±20.3 years in patients admitted for OSA as primary diagnosis (n=32,010) and 63.7±17.6 years in patients admitted for OSA as secondary diagnosis (n=164,759). The most common secondary diagnoses for patients discharged with a primary diagnosis of OSA was arterial hypertension (19.0 %), obesity (16.9 %), disorders of lipid metabolism (8.01 %) and diabetes mellitus (6.48 %). The most common primary diagnoses for patients discharged with a secondary diagnosis of OSA were obesity (12.5 %), heart failure (9.6 %), and chronic J. de Miguel-Díez (*) : L.
